Introduction: The present clinical case describes periapical microsurgery with an endoscope and microscope in a patient already treated 25 years ago due to persistent periapical disease of the two central upper incisors, restored with poorly adapted crowns. . The first periapical surgery had been performed with silver amalgam as a retrograde filler material, causing grayish staining of the buccal mucosa. Periapical surgery was performed raising a submarginal flap with ostectomy and apicoectomy, retrograde cavity preparation with ultrasound tips, and filling with mineral trioxide aggregate (MTA). After soft tissue healing and complete bone regeneration of the lesion, retreatment of the incisors with a fixed prosthesis was carried out, adopting the biologically oriented preparation technique (BOPT).
Conclusions: The described periapical microsurgery approach with magnification and illumination of the surgical field was found to be effective, avoiding the need to extract the two central upper incisors.

The impact of root end filling material type and the application of bone graft on healing of periapical tissues after endodontic microsurgery (a clinical randomized controlled trial).

Article Synopsis
- The study assesses how combining various bioactive root-end filling materials with a composite bone graft influences healing in periapical tissues following endodontic microsurgery, using a triple-blinded clinical trial design.
- 56 patients, aged 20 to 50 with specific dental issues, were randomly divided into two main groups based on root-end filling materials (MTA vs. TotalFill) and further split into subgroups with or without bone grafts.
- After 12 months, the results showed no significant differences in healing or success rates across the groups, with no adverse effects reported.
Clinical outcomes of using operating microscope for alveolar ridge preservation: A randomized controlled trial.

Article Synopsis
- The study aimed to compare the effectiveness of using an operating microscope (OM) versus dental loupes (DL) for alveolar ridge augmentation (ARP) after tooth extraction, focusing on wound healing and bone quality.
- Forty teeth from 33 patients were randomly divided into two groups; one received treatment with OM and the other with DL. Results showed that the OM group had significantly fewer tissue remnants and better healing scores at 2 and 4 weeks post-surgery.
- By the 12-week mark, both groups had similar bone healing and quality results, suggesting the early benefits of OM in reducing tissue remnants did not translate into long-term differences in bone health.

Endodontic microsurgery (EMS) is an alternative treatment option for previously treated teeth with persistent periapical disease, offering a favorable prognosis. However, it can be particularly challenging in anatomically complex cases, risking unintentional damage to adjacent critical structures. Dynamic navigation (DN), a computer-aided technique, facilitates precise presurgical planning and provides real-time guidance during operation.

Endodontic treatment, essential for preserving teeth affected by pulp or periapical diseases, often encounters challenges such as complex root canal anatomies and calcifications that can hinder success. Traditional techniques, although effective, are limited in addressing these complexities. Guided endodontics, which utilizes advanced imaging and navigation technologies, promises enhanced accuracy and precision, potentially improving treatment outcomes.

Background: In clinical practice, the buccal approach is typically the primary choice for endodontic microsurgery. Owing to the thickness of the buccal bone plate, the distance between the buccal bone plate and palatal lesion location, and soft tissue traction, the palatal approach may be more suitable for microsurgery for apical periodontitis of the palatal roots of the maxillary molars. However, the length of the palatal root, location of the greater palatine artery (GPA) and foramen (GPF), and surgical field of observation make palatal surgery challenging.
